With huge page support you do have two different page sizes, but the only
code that uses those defines currently is in the x86 shadow mmu code,
so I am fine with moving gfn_to_index() into x86 specific code and getting rid
of those defines (you will probably need them when you will implement
nested HYP mode :)). But can you do it as a separate patch series and
remove the defines for all arches?
